Bowhead whales are among the few baleen whales that remain primarily within Arctic and sub-Arctic waters throughout their lives.
In 2016, researchers attached satellite transmitters to bowhead whales in western Greenland. Movement data showed annual migration routes exceeding 10,000 kilometers between feeding and wintering grounds. Whales traversed Baffin Bay, Davis Strait, and high Arctic passages. Seasonal ice extent strongly influenced travel timing. Tracking provided detailed route maps previously inferred from sighting records. Individuals displayed consistent return patterns across years. Migration corridors aligned with plankton productivity zones. Long-distance travel occurs despite ice barriers and extreme weather. Arctic megafauna navigate basin-scale environments with precision.

Migration mapping enhances international cooperation across Greenlandic and Canadian waters. Cross-border data sharing supports unified conservation strategies. Shipping advisories depend on accurate seasonal movement forecasts. Satellite telemetry reduces uncertainty in stock management. Long-range travel complicates jurisdictional oversight. Ecological connectivity spans multiple nations. Arctic governance must operate at ocean-basin scale.
For bowhead whales, migration is routine rather than exceptional. The irony lies in animals crossing vast distances guided only by environmental cues. Ice and plankton define their itinerary. Human borders mean little beneath shifting seas. Arctic corridors function as seasonal highways. Giants trace invisible routes across frozen oceans.
